I also hate the munch words as applied to humans, but sometimes munch, munchy, munchies are appropriate, when humans are eating a bit as bovines do. A while back, bixa mentioned "crispy" - "crisp" is a much crisper word.
No words per se send me into a tizzy. My father cringes at the use of "tasty" for some reason. However, I object to words being used incorrectly. Friends know never to use the word "impact" as a verb around me. I'm so last century, I know, but it just sets my teeth on edge. I won't even get into "impactful".
I agree with LaGatta that munch would occasionally be appropriate, but yeah, it is somehow irritating.
The food-related word that I hate is "sip". WHY in every reference to tea, are people always sipping it? It has such an annoying raised-pinky tone to it.
I've ranted elsewhere about "veggies" (almost puked writing that), but any baby talk word by adults sets my teeth on edge. This one may be dying out, thank goodness: "pooter" instead of computer. Wouldn't pooter be something one does after eating beansies?
When I mentioned "crispy" (shudder) earlier, it was to point out that crisp is all the word that is needed. Saying "crispy" is tantamount to saying "funnyy" for funny.
Lizzy, strangely enough the word delicious used to affect me the way that tasty affects your dad. What I hate is tasty used to describe things that aren't food. Ditto edgy used to mean cutting edge instead of um, edgy.
What makes me crazy about horrific and any form of gift-used-as-a-verb is how those words get glommed upon and used ad nauseam. It makes the users sound so mindlessly copy-cattish. Everything now is "horrific", to the exclusion of appalling, atrocious, awful, dreadful, frightful, ghastly, grisly, gruesome, hideous, horrendous, horrid, horrifying, lurid, macabre, monstrous, nightmare, nightmarish, shocking, terrible, or any other word that served perfectly well in the recent past. Ditto gift-as-a-verb. Why? If I give someone something, I did not lend, sell, trade, nor rent it, which makes it a gift -- which means I don't need to beat listeners over the head with the concept by saying I gifted it. And hearing that someone was gifted with something makes me wish I didn't even know English so I'd never have to be that irritated again.

The word that grates on me is the pronunciation of "mischievous" as "mischeevy-ous". Once the sign of poorly educated it is now creeping in to TV and radio talking heads, thus giving it credibility. My kids used to wind me up by using it deliberately to get my response.
